1. Open Terminal and type the following command using the name of your network connection to disable IPv6.
Mac OS 10.7 - 10.11:
Code: Select all
networksetup -setv6off Wi-Fi
Code: Select all
networksetup -setv6off “Wi-Fi”
2. Verify that IPv6 is disabled in Network Preferences. Go to System Preferences -> Network -> network connection Advanced -> TCP/IP and check IPv6 is set to Off.
Note: The old method of disabling IPV6 shows 'Off' in the IPV6 selection menu, however this is not included in later versions of Mac OS X since IPv6 will be used more over time.
